<p>PROBLEM TO BE SOLVED: To provide a solenoid which can prevent the loosening of a nut, when a coil ass'y and a tube ass'y are fixed with the nut. SOLUTION: A solenoid 1 has an outer case 3, a coil ass'y housed in the case 3, and a tube ass'y 9 passed through the coil ass'y 5. The coil ass'y 5 has a hollow bobbin 6 and a coil 7 wound around the bobbin 6, and the tube ass'y 9 has a fixed core 10 arranged on the front side, a pipe 14 which is formed closed when a stopper 16 is fixed to the rear end section of the pipe 14, and a movable core 12 which is arranged in the pipe 14 in a slidable state. The stopper 16 is protruded backward from the outer case 3 and has a male screw 16a. A nut 19 is engaged with the male screw 16a, and an elastic collar 20 which is bent so that its both end sections 20a are opened outward is provided between the rear wall 3b of the case 3 and the nut 19. When the nut 19 is tightened, the both end sections 20a of the collar 20 bend in the axial direction and prevent the loosening of the nut 19.</p> |
